Extended Data Fig. 1 | DSA-10 images. Dirty and deconvolved images
are shown of two bright point-sources and FRB 190523. All data were
obtained at the same hour angle relative to the meridian, within 12 h of
each other. The same calibration solution, derived using the J1200 + 7300
data, was applied to all data. The black crosses indicate the known
source positions in the top and middle rows, and the best-fit position
of FRB 190523 in the bottom row. The recovery of the correct position
of J1927 + 7358 at the hour angle that FRB 190523 was detected at
demonstrates the accuracy of the calibration solutions.
